Add IC#closeConnection(). It turns out that BaseInputConnection has still depended on a private API named BaseInputConnection#reportFinish(), which was introduced 4 years ago to work around a UI freeze due to an unbalanced batch edit count [1]. Note that such an unbalanced batch edit count cannot always be avoidable. It can easily occur in the following situations. - The current IME crashed during batch edit. - The user changed the View focus during batch edit. - The current IME called IMM#switchToNextInputMethod() during batch edit. The remaining problem is that #reportFinish() is still an internal API and only subclasses of BaseInputConnection can implement it, and IMM calls it when and only when the current InputConnection is BaseInputConnection or its subclass. InputConnectionWrapper and any other InputConnection implementations will never receive such a callback to clean up InputConnection#{begin, end}BatchEdit(), which is considered to be a major contributor to UI freeze. To address the above issue, we unhide BaseInputConnection#reportFinish() as InputConnection#closeConnection() so that application developers can receive an appropriate callback to clean up internal state including unfinished batch edit.

Tell IMS about missing InputConnection methods. Summary: This CL introduces a unified mechanism to deal with the situation where the application directly implements InputConnection but some of methods are not implemented. Note that there should be zero overhead when the application extends BaseInputConnection or InputConnectionWrapper. Background: When ever we add a new method to InputConnection, there has been a risk that existing applications that directly implement InputConnection can get java.lang.AbstractMethodError exception at runtime, because older SDKs do not require the application developer to implement the methods that are newly added in later SDKs. Because of this we strongly discouraged developers to directly implement InputConnection interface, and encouraged them to subclass BaseInputConnection or InputConnectionWrapper instead. That said, as requested in Bug 26945674, there is a certain demand to be able to implement InputConnection without depending on BaseInputConnection. The goal of this CL is to provide a reliable and sustainable solution to above missing method scenario in InputConnection. One of the reasons why dealing with missing InputConnection methods is so difficult is that what InputMethodService receives to communicate with the target application is actually a proxy class com.android.internal.view.InputConnectionWrapper that runs in the IME process and immediately returns true for most of methods in InputConnection such as #commitText() and #finishComposingText(). Because of this asynchronous nature, it is too late to change the actual return value that the IME receives when the application receives those one-way asynchronous IPC calls. Solution: To handle those cases, this CL checks the availability of InputConnection methods that did not exist in the initial release before the target application calls startInput(), and let the application to send its availability bits to IMMS so that InputConnectionWrapper running in the IME process can be initialized with such availability bits. Note that we do know that BaseInputConnection and its subclasses support all the InputConnection methods, hence for most of applications we can just assume that all the methods are available without reflection. With such availability bits, InputConnectionWrapper is now able to gracefully return failure code to the IME because the availability of those methods is immutable, except for a tricky case where the application relies on a proxy object that dynamically changes the dispatch target. Here is the list of APIs that we start checking the availability in this CL. [API Level 9+] - InputConnection#getSelectedText(int) - InputConnection#setComposingRegion(int, int) [API Level 11+] - InputConnection#commitCorrection(CorrectionInfo) [API Level 21+] - InputConnection#requestCursorUpdates(int)} [API Level 24+] - InputConnection#deleteSurroundingTextInCodePoints(int, int) - InputConnection#getHandler() Ideas alternatively considered: Default methods in InputConnection We once considered having default methods in InputConnection but abandoned this idea because it does not directly solve the problem about how to tell the that the API does not take effect. Also having default methods would make it difficult for application developers to be aware of newly added methods in InputConnection.

Introduce InputConnection#getHandler(). Currently there is an internal hidden class named ControlledInputConnectionWrapper which works as a proxy in the application process to receive incoming binder calls from input method and dispatch those method calls again on an appropriate thread. Although this is a kind of implementation details, basically you can see the same design everywhere in the Android. Currently ControlledInputConnectionWrapper is initialized with view.getHandler(), where the view here is the View which was used to call View#onCreateInputConnection(). This is actually a reasonable behavior because we have generally assumed that there the only reasonable way to implement InputConnection is to extend BaseInputConnection, which is designed to be able to work only on the UI-thread associated with the target view. However, on Android N and onward, we are going to ensure that BaseInputConnection can be re-implemented on top of public APIs [1]. Although most of applications should not try to do that, for certain applications such as web browsers and WebView it may make sense to let custom InputConnection implementation run with a custom Handler so that the application can respond to the IME without blocking the UI thread. To do that, this CL introduces a new method InputConnection#getHandler(), which changes nothing as long as it returns null, but if it returns non-null Handler, InputMethodManager will use it to initialize ControlledInputConnectionWrapper. Note that InputConnection#getHandler() is not for IME developers. It just returns null when called in the IME process. [1] See Bug 24688781 for details.

Introdude IC#deleteSurroundingTextInCodePoints(). This CL introduces a API variant of IC#deleteSurroundingText(), named IC#deleteSurroundingTextInCodePoints(). Major differences from the existing one are: - The lengths are supplied in code points rather than code units. - This API does nothing if there are one or more invalid surrogate pairs in the requested range. (Failure Atomicity) Note that due to the asynchronous nature of the input method architecture in Android, implementing the same logic in the input method side basically ends up with unreliable and unpredictable results.

Enrich JavaDoc for IC#deleteSurroundingText(). As a preparation work for Bug 6526420, where we are going to introduce a new variant of IC#deleteSurroundingText(), this CL attempts to clarify about the expected behavior of IC#deleteSurroundingText(). With this CL, the expected behavior when the number of existing characters is smaller than the number of characters to be deleted is now documented by simply describing the current behavior of BaseInputConnection, that is, IC#deleteSurroundingText() will delete characters until it deletes requested number of characters in code units or reaches to an end. This is purely documentation work. No behavior change is intended. Bug: 6526420 Change-Id: I7280dec07e1c043bd26b3b12fd866b9d8b6186cc

Remove CursorAnchorInfoRequest and related stuff This CL removes CursorAnchorInfoRequest and related stuff in favor of InputConnection.requestUpdateCursorAnchorInfo, which is more easy to understand. This CL also deprecates InputMethodManager#updateCursor and related stuff. Rationale: 1. The spec of #updateCursor says that it provides the cursor position in local coordinates, while the input method requires it in the screen coordinates. 2. #updateCursor has never been enabled in AOSP, because InputMethodManager#isWatchingCursor always returned false. 3. There has been no way to let InputMethodManager#isWatchingCursor return true. 4. In L, InputMethodManager#updateCursorAnchorInfo is introduced to address all the issues above. Given that we no longer need to support #updateCursor, CursorAnchorInfoRequest is overkill when we need to convey just a couple of parameters.

Polish new IME API for L part 2: CursorAnchorInfo This CL addresses feedbacks from internal customers for new input method APIs that are mainly used for physical keyboard support in L. For performance reasons, #onUpdateCursorAnchorInfo is not called back by default and each input method has to enable this event notification explicitly whenever fine-grained character locations are needed. In L-preview, InputMethodSession#setCursorAnchorMonitorMode was introduced for this purpose. However, we got several feedbacks to be addressed. - The effect of #setCursorAnchorMonitorMode is not preserved during focus change. IMEs need to call #setCursorAnchorMonitorMode every time when #onStartInput is called. This is tricky and hard to understand. - As #onUpdateCursorAnchorInfo is a new API, not all applications/text editors have supported it. Therefore IMEs can't always rely on it. However, there is no way to query if the attached target is supporting this new API or not. It would helpful for IME authors if we can provide a reliable way to query if the attached input target is supporting the new API or not. In order to address these issues, the triggering method has moved from InputMethodSession to InputConnection in this CL, as an analogy of existing InputConnection#getExtractedText API, which has provided similar functionality including optional reactive event callbacks from the application to the IME.

Add methods to InputConnection: setComposingRegion() to select a region of text for correction, and getSelectedText() to return the selected text. setComposingRegion: The TextView may choose to highlight the text in some way (underline for now) to indicate that the text is selected for correction, if the IME wants to provider alternatives. Choosing an alternative in the IME can then call IC.commitText() to replace the highlighted (not selected) text with a different candidate. This change also ensures that any existing spans/styles are not wiped out. So we can now correct rich text as well. getSelectedText: This is a convenience to get the selected text instead of using extracted text that is more heavy weight. Existing getTextBeforeCursor() and getTextAfterCursor() fail to retrieve the selected text, only what's before and after the selection. Change-Id: Ieb5ecd5ff947ea04958589f501e7bd5228e00fb5
